Dockerize Xml file folders and scripts from tazendra

[valearna]

To be mounted as volume (we could use same format as user_files in curation_forms):
main location on tazendra: /home/postgres/work/pgpopulation/wpa_papers/pmid_downloads/

files/dirs needed:

• done
• xml
• rejected_pmids
• removed_pmids

script to be dockerized:

• get_new_elegans_xml.pl

Not sure we need to do this, depends on timing of when we switch over to dockerized tazendra vs WB SoT to ABC.

We have done this but we don't remember if we tested it or not @vanaukenk
